Title: Image forming apparatus
Inventor: MORITA HIROSHI
IPC: G03G21/00
Filed: 2019-06-06
Abstract: To achieve both image formation with a uniform density across the entire area in a conveyance direction of a long recording material, and prevention of deterioration of a developing roller and a photoconductor drum.SOLUTION: A control unit sets a speed ratio to a first speed ratio (S3), and starts an image forming operation (S4). When the length in a conveyance direction of the recording material is equal to or more than a predetermined length (YES in S5), and an image ratio is equal to or more than a predetermined value (NO in S6), upon arrival of a sub scanning direction position at a change position (YES in S7), the control unit changes a peripheral speed ratio from the first speed ratio to a second speed ratio larger than the first speed ratio (S8). By increasing the peripheral speed ratio, even if insufficiency of toner supplied to a developing roller occurs during the image forming operation, an image density does not fall below a density at which a user can determine a difference in density by visual inspection until the rear end in the conveyance direction of the recording material is reached. Thus, image formation with a uniform density across the entire area in a conveyance direction of a long recording material, and prevention of deterioration of a developing roller and a photoconductor drum can be achieved.SELECTED DRAWING: Figure 4
